ios vs. Android: The twin futures of mobile net
What is open-source software?
This refers to software of which its source code has been made available to anyone for any purpose. This grants customers the right to change, develop and distribute the software for any purpose.
As seen in the above analogy, Android is an example of an open-source system.
So, closed-source software is source code that has not been published and made publicly available. Customers do not have the right to change or distribute the software in any way.
Apple is a closed-source system.
